Mathematical Treasure: Appell and Goursat’s Analysis

Paul Appell (1855-1930) was a French analyst and geometer. In 1895, he and another French analyst, Édouard Goursat (1858-1936), published Théorie des fonctions algébriques et de leurs intégrales: étude des fonctions analytiques sur une surface de Riemann (Theory of Algebraic Functions and Their Integrals: Study of Analytic Functions on Riemann Surfaces). This book provides insights into mathematical research concerns of this period.

The introductory section of the text reviews important definitions and theorems concerning functions of a complex variable.
